mlxme-mAci-uuzt g'an, have invented a new and useful Mixing.

Machine, of which the following is aspeci cation.

This invention concrete.

" The object of the inventionis to provide a;

mixing-machine in which the mixing of ma terials will in a novel manner bepositively secured with a minimum of labor and maximum of speed and in which hydration of the materials shall be effected in such manner as to cause the resulting product to be homogeneousthroughout, I

With the above and other objects in view, as will appear asthe nature of the invention is better understood, the same consists in the novel construction and combination of parts of a mixing machine, as will behereinafter fully described and claimed.

In-the accompanying drawings, forming a part of this specification, and in which like characters of reference indicate corresponding parts, Figure 1 is a view in" vertical longitudinal section through a, machine constructed in accordance with the present invention. Fig. 2 is a viewinfront elevatron of a portion of the apparatus.

Fig. 3 is a horizontal section taken on the line 3 3, Fig. 1, and looking in the direction of the arrow thereon; =Fig. 4 183 fragmentary detail -view in plan of a portion of the machinel.

1 Referring to the'drawings, l'de'signates the base or body of the apparatus, which is pref erably cylindrical in shape 'and is provided near its lower end with a door 2. Arranged within the casing isa series of charging-hoppers 3, 4, and 5, which, as shown in per .3, which will preferably be made of castirony-has combined; withv it twoupstanding arms ,or projections 6, that formbeai in s for a'drive-shaft 7, carryin at one end a rive.- wheel 8, intermediate 0 I ion 9, andatits other end a s rocket-w eel;

.16 and a crank 11. Thesaid opper is further provided an upstanding 'iri'arginal flange 12,froni one sideof which projects a:

bracket 13, having formedin-aits outer end a bearing for-one end ofa vertical shaft 14, the

" other end of which works ina step-bearing g I relates to mixing-machines such as are commonly employed in mixing of lug. 1, are e T e'hop- .ing mounted for rotation in keepers 34,.se'

carried by thebotto m' 16 of the casing and I being also inverted-truhcated-cone shaped,

the bearing being supported by a plurality of arms 17, which are preferably cast integral with the bottom and the bearin Of course it-will be understood that the be, may be made, as separate elements an com bined with the bottom, and as this will be apparent detailed illustration of such obvious modification is omitted. T he'bott-orn is provided with two marginal flanges 18 and 19, disposed atright angles to each other, the

flange 18' being. disposed in a vertical plane arin -arrns and forms a seat forthe lower end of the casin which isheld combined therewith by bo ts 20; The flange 19 rests upon the base of a receptacle 29 of the apparatus and is held combined therewith by bolts 22. The

base 21 is a box-like structure and is provided at its forward end with a mouth 23, through which the material that falls into the base maybe removed The .baSeQhas' combined with it two cranks 24, one disposed on each side thereof adjacent to the mouth, and each crank carries-a curved slotted annl-25andan axle 26'for supporting wheels 27 the cranks being pivotally combined with the base in any preferred manner, as bybolts or rivets 28, i

The slots in the arms are engaged by bolts 29,. which carry thumb-nuts 30 'to lock the arms at any desired adjustment. Thejarms are provided for the purpose of; ermitting' one end f the base to be low'e're to the "round when the machine 'is'in'operation, t us to prevent movement, and when it is desired to transport the machine the cranks are moved to the position shown in Fig. 1 and by tightening thethumb-nuts the adjustment of the parts will remain fixed. The rear end of the base has combined with it a shaft'31, provided. at its 1owerend. with a fork 32 between which is journaled a wheel 33, the shaft becured to'ithe base. The fork has combined with it a handle 35, by which the apparatus ma be drawn.

stand the jars and Vibrations to which the ap.---

paratus will be. subjected in use.

Combined with the Shaft- 4. is was of discharging-disks 38,- three being shown in IIO the proper operation of the machine.

this instance and being hollow inverted-coneshaped structures having imperforate bottoms with which are combined lugs 39, carrying set-screws to permit adjustmentof the disks 4 relatively to the hoppers} The lower hopper has combined with it a plurality of series ofrakes or stirrers 41 (one series only being shown) to insure the removal of-all material that drops to the bottom 16, whence it escapes through theeentral opening 42 therein into the base. Surrounding the exterior of the casing' at a point adjacent to the base is a'p'ip'e 43, having perforations registering with perforations 44 111 the walls of the casing, and connecting with the pipe is a hope 45, which leads to a suitable ,water- PP Y- It will be'noted by reference to Fig. 1 that the flare of the'walls of the discharging-disks is more acutethan those of the charging-hoppers,this being necessary in order to secure In driving the apparatus either the crank 11 may be employed or a sprocket-chain driven from a suitable-source of power may be combined with the sprocket-chain 10; Upon the shaft 7-beingrevolved the motion from the miter-gear 9 is transmitted to' a similar gear 46, carried by the shaft 14, and this latter causes the discharging-disks rapidly to'iotate and forthe scrapers 41 to travel over the bottom and miX'and .di'slodgegthe material thereon and discharge it into the base. The materials are fed first to-the'hopper 3, whence they pass-to the upper one of the dischargingdisks, and from this, owing to the centrifugal action, they are discharged and fall back through. the second charging.

hopper 4, thence to the next discharging-- disk, thence to the charging-hopper 5, and thence to the bottom discharging diskpvhen'ce they are discharged upon the bottom 10. As

- the'materials are'discharged from the bot tom disk they pass through jets of Waterthat issue 'through the openings 44, and thus become thoroughly hydrated, after which they described.

The operation of the machineis continuous I and very. rapid and will effect the mixing of.

the materials in a manner that will be thor- 4 ough and effective.

use is not to be limited to this function alone,

as it may be employed in mixing any substance or substancessuch as seeds, grain, flour, and the likeand still be Within the Having thus described the invention, what is claimed is 1. In a-mixing-machine, a base constituting a receptacle, a casing supported by the base andhaving aninverted-cone-shaped. bot tom provided with an orifice discharging into the receptacle, a step-bearing supported by the bottom and arranged over the orifice, a plurality of cl iarging-hoppcrs rigid with the casing, the upper one of which is provided with upstanding and lateral bearings, a drivesh'aft mounted in the upstanding bearings, a vertical shaft engaging the step-bearing and the lateral bearing,-intermeshing miter-gears 'carried by the two shafts, and dischargingdisks-carried by the vertical shaft.

2. In a mixing-machine, a base constituting. a receptacle, a casing supported by the base and having an inverted-eone-shaped bottom provided with an orifice discharging into the receptacle, a step-bearing supported by the bottom and arranged over the orifice, a plurality of charging-hoppers rigid with the casing, the u per one of which is provided with upstanding and lateral bearings, ,a drive shaft mounted in the upstanding bearings, a vertical shaft engagingthe step-bearing and the. lateral bearing, internieshing DIliLGT-QOMS carried by the two shafts, discharging-disks carried by the verticalshaft, and a water- ,supply pipe surrounding the'lower portion of the casing and havin orifices registering with similarorificesin't ec'asing.
